M38 starter switch

Post by Radtech » Sun Sep 10, 2017 4:25 pm

There are 2 guys selling M37 marked starter switch housings in epay claiming they will fit the M38 and 38A1.The bases are too large and they have an extra copper tab on the inside.Anyone know what that extra tab is for on the M37

It is too large for any of the M38 starters.The early M38 has a totally different switch .I made the mistake of buying one.I have no idea what the extra 2" copper tab attached to one of the posts is for.It has a G741 part number.

I tried to make sense out of the G-740 and G-741 ORD9, the numbers seemed to have meaning in the index, but would not surface in the illustrations.

It is 3/16" too long and has a copper tab 2" long attached internally to the starter side terminal.

You are looking for the whole early starter or the switch housing? Can't promise, but I'll look Saturday.

I have the late type starter on my M38.Years ago my father told me in 1956 they had an MWO to change all of the M38 starters to the late type.They changed every M38 that had the early starter to the late type.

Well sort of, the early starter system stayed until the early engines with them need sevice at the support units. Late M-38 was factory equipped with the G-758 Starters, bell housing and Ring gear.

My father was a mechanic in the Air force from 1947-1988.he told me the Air Force issued orders in 1956 to change out all of the early starters on every M38 in service.He told me there was no explanation as to why only that they were ordered to change them all.All the early starters,bell housings and ring gears went to the salvage yard.
